Meghan Markle's future title

When it comes to gaining British citizenship, Markle will be treated like anyone else according to Kensington Palace.

Prince Harry's communication's secretary, Jason Knauf, said Markel, who has moved to London from her home in Toronto, would be "compliant with immigration requirements at all times".

To become a British citizen, the bride-to-be must demonstrate a good mastery of English and life in UK.

Markle will not hold every right enjoyed by other UK citizens, such as voting and political expression, after tying the knot with Prince Harry and obtaining her UK citizenship.

The bride-to-be also can't be called Princess Meghan after the marriage, because due to rules governing the British crown, only those born into the royal family can use the title Prince or Princess, followed by their first name.

It is a royal tradition princes of the realm and their spouses get new titles on their wedding day.

Their titles are entirely up to the Queen - there is no strict protocol, and only a loose tradition to go by.

Most royal observers think the couple will be named the Duke and Duchess of Sussex.
